LOALL PERSONS TO WHOM THESE PRESENTS MAY-COME:

Be it known that I, HENRY M. BEECHER, of P1antsville, in the county of Hartford, and State of Con necticut, have made anew and useful invention having reference to the Manufacture of Blanks for Carriage-Shaft Couplings; and I do hereby declare the same to be fully described in ther-following specification, an'd represented in the accompanying drawings, of` which-@ Y Figure 1 exhibits the top view of a. strip of metal as formed for being converted into blanks.

Figure 2 is a top view of one of the blanks as cut by the bending-machine, to'be hereinafter described.

Figure 3 is a front elevation, A

Figure 4 a top `fiew,

Figure 5 a side elevation, and

. Figure 6 a horizontal section of thesaid machine, used for creasing or cutting and bending the blank. Figure 7 is a side elevation of the blank as it appears withl'its wings after having been bent o ut by thev bcnding-maehine. i A

Figure 8 is a top view of it as finished in a drop-press.

Figure 9 is a top view, and. l

Figure 10a side elevation of the blank as it appears with its wings subsequently bent up into parallelism with each other. i

In carrying out the process or method of making the blank, I first reduce by dies a strip of sheet metal to the form shown in iig. 1, which consists of a series of U-formed parts, A A A` united by shanks or connections, B B B. p

Next, the shanks are to be cut on the lines Va a a, so as to divide thestrip into several part-s, each having the external form shown in iig. 2.

Next, each of such parts is to be creased or cut and bent by the bending-machine. This machine consistsof two long levers, C C, jointed together at their inner ends, their connection-'pin :c being extended up from a lat base, D.

A straight creaser or cutter, E, projects up from each' of the levers, so as, when the levers are closed together, and held in place by pins y' y, inserted in the 'base-plate, to come directly underneath one of two creasers or cutters, F F, extended down from a follower, G,so,applied to a.standard, I'I, (erected on the base, 1),) as to be capable of moving,r vertically therein. A

The extent ofupward departure or movement of the two levers, with respect to each other, is determined by two stops or pins, d CZ, extended upward from the base, D.

The purpose of the two pairs of creasers or cutters is to 'effect cuts in and through the part A, as representedat e e in fig. 2, such being accomplished by laying the part A on the lower creasers when thelevers are. closed together, and subsequently forcing,r the upper creasers or cutters or the carrier downward, so as to cause both pairs of creasers or cutters to out through the metal, such being done while it is in a red-hot state.

Next, the upper pair of creasers should be raised away from the metal, and the levers of the lower pair of such creasers should be moved apart by their handles, and on their common fulcrum, so as to bend each of the portionsffout into a right or nearly a right angle with the shank B, or, in'other words, into theposition with respect to it, as shown in tig. 7. It will thenbe ready for beingr nished or further shaped by dies in a drop-press.

I claim; the above-described process or method ofr making the shaft-connection blank, the same consisting in forming it with the head part A and the shank B, and subsequently cutting it through on the lines e e, and finally bending the portionsff around into right or nearly right angles with the shank part B.

I also claim the machine, substantially as 'described, for creasing or cutting the blank, and bending the portonsffof it around into or nearly into right angles with the shank, such machine being composed of the bed-plate and standard, the two levers, the follower, and the two pairs of crasers `or cutters, the whole being` arranged for use in manner as specified.

' HENRY M. BEECHER.
